From cacd05805eeea393ec929fe841f9a68aa2140d92 Mon Sep 17 00:00:00 2001 From: Mark Cave-Ayland Date: Thu, 21 Dec 2017 07:32:57 +0000 Subject: [PATCH] apb: remove pci_apb_init() and instantiate APB device using qdev MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit By making the special_base and mem_base values qdev properties, we can move the remaining parts of pci_apb_init() into the pbm init() and realize() functions. This finally allows us to instantiate the APB directly using standard qdev create/init functions in sun4u.c.
